View Full Version : Random disconnections from a Terayon TJ715x cable modem?

Hi.

Since beginning of this month, I have had random disconnections that
occur twice/trice (seems like every 10-14 hours? There are no exact
times and not temperature related in the room [can happen when cool like
70F degrees and hot like 85F degrees) a day ever. I seems to have
narrowed it down to the cable modem when I did nonstop pings (one per
second) a few times. Example of one that occurred recently:

....
64 bytes from 192.168.100.1: icmp_seq=837 ttl=59 time=4.61 ms
From 192.168.0.1 icmp_seq=838 Destination Host Unreachable
From 192.168.0.1 icmp_seq=839 Destination Host Unreachable
From 192.168.0.1 icmp_seq=840 Destination Host Unreachable
From 192.168.0.1 icmp_seq=841 Destination Host Unreachable
64 bytes from 192.168.100.1: icmp_seq=842 ttl=59 time=5.56 ms
....

I also pinged from outside to my IP address and had a couple packet
losses. I tried pinging my old Netgear RT311 router, rebooting all
hardwares, changing network cables, etc. None of those fixed/decrease
the problem. I also checked my Terayon TJ715x cable modem's logs after
these random disconnections, and none of them show reboots from them.

Is my cable modem going bad? Speeds are fast for the normal package
user. It is just annoying random disconnects right now.

Thank you in advance. :)

Hello:

Can you monitor your cable modem's receive power level and receive
signal-to-noise ratio for awhile? Also, just after you've received
a disconnect would be good too.

Before you monitor those, perhaps you could tell us what those
instantaneous values are now.

Let us know what you find.

Best wishes to you.

If you have Perl, I have a script that can read out the web pages on your
TJ715X - let me know where to email it if you like. If you don't already
have the password, it's: icu4at!

RF Parameters
Parameter Value Units
Tx Power 44.2 dBmV
Rx Power -1.9 dBmV
Downstream SNR 33.4 dB
Downstream MER 32.4 dB
Tx Frequency 33000000 Hz
Rx Frequency 705000000 Hz

Does that looks OK? I can't check it during the quick disconnections
since I can't even connect to the cable modem and even if I could, it
goes too fast. I will check again right after disconnections if I am at
the computer and noticed it. It is hours ago for the last one overnight,
so I will have to wait for the daytime one.

Sure, I have Linux. Can you please kindly post it in http://pastie.org/
or somewhere? However, what happens if my cable modem disconnects when
the event happen? I won't be able to get the reading during the quick
disconnections. :(

Initially, I wished to know if your cable modem was running on the
ragged edge. However, this does not appear to be the case. When you
think about, try looking at these levels again to see if any significant
deviance shows up. Although the cable modem hasn't been entirely
eliminated from the equation, I would look elsewhere, for now.

My own numbers are -6.3 dBmV & 34.1 dB SNR (downstream) this morning.

For a short time, could you experimentally bypass your router, such that
your Linux system's NIC is directly connected to your Terayon cable
modem?

Do any of your system logs have anything interesting? dmesg? Are you
using the USB port on your modem, or the RJ45 Ethernet connection?

You haven't /yet/ eliminated your cable modem, nor has your ISP's
outside plant been ruled out. But hopefully, you can continue to divide
and conquer.

I can try that, but I will need to secure my box since my router
protects my computer and I will have to rewire my ethernet cat5 cables.

No, like I said my cable modem disconnects my LAN. I lose connections on
all computers. My router is fine (no disconnections from pinging
192.168.0.1 from what I saw).

I think I had a disconnection an hour ago or so, but it might be too
late:
Tx Power 44.7 dBmV
Rx Power -2.0 dBmV
Downstream SNR 33.5 dB
Downstream MER 32.6 dB
Tx Frequency 33000000
Hz Rx Frequency 705000000 Hz

You don't know that from pinging your router - just because you can
talk to the router, doesn't mean it's passing data. You haven't done
anything to isolate it until you remove the router from the equation as
1PW suggests. You could kook up a Windoze PC with a software firewall
direct to the modem and test with that - it should give you sufficient
protection.

PS: What kind of router is it ?

To a larger extent than a Windows system, your Linux system is best
situated to endure an attack without much work on your part. If you are
of the belief that your cable modem is failing (not a bad guess) then
consider the following:

If you are leasing from your provider, maybe you could save the price of
an on-site call by going to their office for a swap of the cable modem.

If you own your cable modem, a replacement can be had for less than $100
or you can ask your service provider for one at about $3 per month.

Thanks. For some reason, I used to get charged for three bucks a month
for leasing the cable modem before Adelphia went busted. RoadRunner
doesn't charge. If I get exchange it, will I be charged again?

If you bought it, you should be able to just put it away and ask for
new one (most likely refurbished) from RR since you're entitled to one.

No need to give them the old one.

OK. I hope they can provision in office too.

I got the perl from Bill, made myself a bash script, and they worked for
a few minutes, but it seems like this cable modem didn't like its Web
pages (listing all) refreshing every two seconds. Now, I can't connect
to 192.168.100.1 (DDoS protection?). :( Does this cable modem have a
feature to block refreshes/reloads or something?

I might need to unplug and replug its power after I get home if it still
doesn't let me in. I am not sure how I can use this script in a loop to
monitor its statistics if it blocks Web connections. :(

My script:
$ more loop
echo -- >> results.txt
echo >> results.txt
date
date >> results.txt
perl -x ~/bin/TJ715.pl >> results.txt
../loop

Strange. I haven't rebooted the cable modem and still cannot connect to
192.168.100.1, but I haven't had a disconnection almost a day! I wonder
if that was fixed by my "DDoS"? LOL. It's too early to say the problem

I take that back (spoke too soon). At about 11:06 AM PDT, I got
disconnected. :P I guess I will unplug and replug it to be able to
access the cable modem later tonight or whenever so I can use the Perl
script (if it lets me refresh/reload every few seconds). [grumbles]

I wished there was a way to reboot the cable modem remotely like my
router.

Hello Ant:

What *does* happen if you try to connect to 192.168.100.1 through your
computer's browser?

If you mean a Web browser, then it just times out and say it didn't
connect like as if a Web site/server was down (e.g., "Alert!: Unable to
connect to remote host."). I tried it with two different computers (XP
Pro. SP3 and Linux/Debian) on LAN last night too. I can ping it and it
responds just fine.

I am pretty sure a reboot will fix it (have seen it do this before with
manual refreshes/reloads). I just can't do it now since I am near it to
unplug and replug the power, and there is no way to reboot it remotely
like my Netgear RT311 router. ;)

Yep, reboots fixed the problem. I reran the script to check and log all
of the statistics every two seconds and my cable modem's 192.168.100.1
stopped responding to my connection after 37 seconds (check every two
seconds).

I made the script to check every one minute (actually 58 seconds since
there are two seconds gap). That seems to be working after 15 minutes so
far. I hope one minute is enough to catch the disconnections. I probably
won't get another disconnection for another 12 hours or so.

I just had another disconnection about ten minutes ago (4:45 PM PDT) and
the Perl script log didn't show anything interesting from what I could

I will have to wait for the next disconnection. I have had checked the

If the Netgear RT311 router was removed from the equation while this
testing occurred, then the Terayon TJ715x cable modem and Road Runner's
outside plant has not been ruled out. While the send and receive levels
have always been OK, I'm a bit surprised to see that your downstream SNR
has taken a 4 dB turn for the worse. Perhaps while you weren't looking,
the receive SNR was even worse too.

I wonder if you have a source for borrowing a cable modem for a day or
so? If so, that's the next logical item to try. If you have any other
services from your cable provider, I would ask if you receive any
intermittent losses of service. e.g. If you have cable based telephone
service, do you experience any voice dropouts from the opposite end.

If you have television service, do you experience losses of signal or
video "tiling" that might coincide with your Internet failures? If you
have any cable splitters or multiport couplers between your cable modem
and your demarcation point, you might consider switching things around
and disconnect/reconnect cables that haven't been touched in years.
Tighten everything with a 7/16" open end wrench such that you use
*slightly* more force than your fingers are capable of. Some of your
oldest F59 connector plugs might be overdue for replacement. RG-59 coax
could be upgraded to good quality RG-6. Do you have any sort of on-site
cable equipment that might contribute to this, or hasn't been mentioned?

Is your cable ingress from a utility pole or underground?

I suppose you could always set aside your own cable modem and rent one
from your provider for a month or so. Comcast, in NoCal, rents ours out
at $3/Mo.

What do you think about all this?

Pete

Hello Bill:

I'm fairly sure it would take me a month of Sundays to adapt the Pearl
script from Terayon TJ715x use to Scientific Atlanta DPC2100 use. Are

I have not tried the router part. Are you saying the 4 dB change for SNR
is that bad? I don't see any 4 value changes in the log parts I posted
earlier.

I will probably go to the local office to ask for a modem exchange since
this was a leased modem during Adelphia days.

If the SA has similar type pages, it shouldn't be difficult at all and
yes, I wrote it (basically a quick and dirty mainly to get my RF page).
It's just a matter of retrieving the pages and parsing the data you want
out of them. The Terayon was reasonably easy as you can probably see
from the code - there's maybe 10-12 lines for each page that's specific
to that page.

Last Thursday, September 30th, you said that your downstream receive sig
was:

"Rx Power -1.9 dBmV
Downstream SNR 33.4 dB"

The receive signal level is fine if it's generally 0.0 dBmV plus or
minus 12 to 15 dB or so. YMMV. Your receive SNR /was/ fair at 33.4 dB,
and would be even better at 35 dB. However you have reported your
receive SNR to be as poor as 29.0 dB today and you might start seeing
receive errors.

Sounds reasonable. I just hope you don't bring home a worse one. This
happened to me with three Motorola HD cable receivers. Just as I was
about to cancel all service, they unpacked a new model for me to "try
just one more time". Now the HD TV is good.

I copied the file and was slightly disappointed to see you hadn't taken
credit for what is obviously a significant undertaking. I very well may
try to adapt your work towards use with a Linksys modem I'm getting. I
have a sensitive part in my brain about plagiarized work but I suppose
credit can still go to $Bill.

I write scripts like that every day that the need arises - I wouldn't
call it significant. I did the same for my Netgear RP614 router, but
it's incomplete due to problems getting the popup status/statistics
pages which I haven't had time to debug. If I need a schedule for my
favorite sports team, I write another one, etc.

While I didn't give Ant authorization to disseminate it, I give you
permission to use it as you will for your own use. ;)

If you need any help, let me know and I'll see what I can do.
Basically what you need to do is take your browser to the page
and dump the source out so you can see what you want to use of

Ah. I haven't had any new disconnections and here's my latest log:
Fri Oct 3 05:20:31 PDT 2008

Diagnostics Page

RF Page
Tx Power 40.0 dBmV
Rx Power -1.0 dBmV
Downstream SNR 32.8 dB
Downstream MER 31.9 dB

Rx Frequency 705000000 Hz


Funny, I can't connect to my cable modem's Web pages again. I guess one
minute gap isn't enough. Sheesh! Is that normal? I don't feel like
powercycling my cable modem right now (just woke up). :D I'll do it later.

Haha. I wonder what they have these days. I have had Terayon (a
non-DOCSIS model before the city's cable was upgraded a few years ago)
and COM21 brands in the last.

Dang it! It looks my cable modem finally bit the dust or something.
Since this morning, cable modem got disconnected when I was moving its
cables and couldn't resynch a for few minutes even after recycling its
power. I wiggled its coax cable connector a little and it synched.

At about 1:15 PM PDT, it went down again and didn't come back (probably
have to go home and wiggle that coax cable again on the modem). I can't
reach it either from outside:

So, 76.167.12.158 (gig14-1-indyca1-ars1.socal.rr.com) couldn't ping my
IP address.

I think I will visit the local office tomorrow to exchange the modem.
And tonight is a dial-up night. :(

And my cable modem came back alive by itself. Yup, history repeats again
and it is signal related. Snipped log from the Perl script:
http://pastie.org/284576

I am still planning to visit the local office to exchange modem tomorrow
since the problems are crazy now. I really hope it is not a cable line
issue!

Lost connections again earlier, but for a little short time. I think it
will keep doing that. It's too late to go to visit the local office
today.

One of your phrases is key; "I wiggled its coax cable connector a little
and it synced." A high probability exists that the RG59/RG6 cable, that
terminates at your cable modem, is intermittently failing. I would
consider asking your provider for a cable that can replace your existing
one. I would *not* buy one from Radio Shack or the equivalent. The
replacement will probably/should be made of high quality RG6 coax, and
have the latest good quality crimped connectors. It certainly wouldn't
hurt to request the provider give you the latest model cable modem with
the latest firmware.

Hope to hear from you soon.

Is that the white coax cable (its printed texts say "Adelphia
Communication E830032A (UL) CATV AWG 063840") that goes from outside to
into the house? If so, then Adelphia's contractors set that line (hope
it is a high quality) up back in March 2001. The house never had cable
TV before so the holes had to be drilled, cables, stapled to outside
walls, etc. This was back when Excite@Home was the service and Adelphia
just took over Century Communications. I assume the contractors cabled
from my room to downstair outdoor (no splitters and stuff).

Heh. I was trying to read the texts on the cable line in my room and my
cable modem decide to lose synchronization. I had to wiggle the
connector to the modem again. It's not loose either.

If the coax is one unbroken piece of cabling, from the demarcation point
to the coaxial connector on your Terayon TJ715x, then it would be
difficult for you to replace that cable. In that case, and if indeed
you have an intermittent connection at the modem end where the male
coaxial connector terminates the cable, then it might be best if your
service provider sends a technician out to trim off a few inches of the
coax and crimp a new male connector on. The other possibility is that
the female connector, on the Terayon cable modem, has become
intermittent and the most reasonable remedy is to replace the modem.

If indeed you exchange cable modems on Saturday, that should further
isolate the trouble for you. Remember to exchange the wall wart power
adapter too.

Yeah, I have the whole box, cable modem, and power AC (why do I want to
keep it?) to return. I haven't had any more disconnections and weirdness
so far since I last posted. I just hope the new modem isn't defected and
stuff. :P Funny how I got my cable bill yesterday so I will save a stamp
today by paying them in person later today.

Oh and I think it is the modem because during those quick disconnections
(1 second long), I can't ping 192.168.100.1 like I said in my original post:

....
64 bytes from 192.168.100.1: icmp_seq=837 ttl=59 time=4.61 ms

64 bytes from 192.168.100.1: icmp_seq=842 ttl=59 time=5.56 ms
....

I don't think a problematic cable coax line would cause that? Would it?
Sounds like a modem problem to me.

If you own that modem, why return it ? If it at least works somewhat, it
gives a semi-workable spare.

I don't own it. It was leased since Adelphia days (2005).

OK! I finally got the new modem (Ambit U10C018) working since 12:40 PM
PDT. Man, it's tiny!

The bad news. I think I got disconnected again like five minutes ago.

So far, it fixed my long desynchronizations I had on Friday so I gave
up and swapped modems on Saturday. I could confirm that touching the
coax cable connector to the cable modem would cause to desynch easily.
Even if I don't touch it, it can do the same like on Friday. It doesn't
feel lose. Did I mention that the coax cable connector's needle/pin is a
little bent? I tried to unbent/straighten it, but it is a little bent. I
don't know if this is related.

After the cable modem swap, I haven't had those desynchronizations
anymore. I only still have those quick annoying one second
disconnections like with the old Terayon modem. I checked the modem's
event logs and nothing odd (nor logged about those quick disconnections)
from them.

I still haven't been able to try the cable modem to a computer/notebook
since others house members use my Internet even at late night hours.
Since it takes 10-15 hours to reproduce the random quick
disconnections, I need to wait when things are quiet (hopefully at the
end of this month). I don't have another router to borrow to try either.

Yep, it is confirmed that my old quick disconnection issue from my old
Netgear RT311 router to the new Ambit cable modem remains:

Nothing in cable modem's Cable Modem Event Log page about the quick

However... Yesterday, I had a couple long disconnections (a few minutes
long) when I was not at home. I don't know if those were related to my
quick disconnections or something else (hopefully just hiccups and
haven't had anymore last night and today so far).

Now it has alot of errors... can anyone tell me how to fix this short of getting a new one? Im currently running on wireless N through my Dlink DIR-655 with matching pci wireless card.. running at 300mbps.. Ive tried removing it from the equation on another PC but I still get same dropping issue.


I have cleared the log before but it looks to me like its got a whole bunch of strange dates O.O anywho.. this is my edit.

Also.. Heres my RF readings

Tx Power 50.0 dBmV
Rx Power 3.5 dBmV
Downstream SNR 33.3 dB

The R.F. side of the cable modem still has not been eliminated. This
includes your house's coaxial cable, connector(s) and your service
provider's outside plant.

A methodical approach must be utilized when a failure occurs such that
the downstream/receive signal level and downstream/receive SNR should be
captured that coincides with the failures.

I am still not absolutely sure that you have been able to log into your
new/Ambit cable modem's web pages. Also, the issue of the house coaxial
cable and its "F" connector didn't seem to have been ruled out.

Can you relay any downstream signal/SNR levels? Do you still have
Internet drop outs if the house coaxial cable/connector are slightly
flexed at the rear of the Ambit cable modem?

I can log in from GUI Web browsers like IE6 and Firefox. However, I keep
missing the quick disconnections to check the statistics and I am
minutes/hours too late. I wished there was a way to log the modem's
statistics every minute like I did on my old modem. Darn modem using
ASP or some funky Web pages to make Lynx and eLinks not render
correctly. Same for logging in (401 errors) with Perl scripts.

I assume you want me to get the levels and other information right after
a quick disconnection. If so, then I will have to try that right after
(seconds later) those quick disconnects. What's more annoying,
statistics are separated by Web pages and not all together like my last
modem. Bah.

What did you mean by flexed? Unscrew and losen the coax connection from
the modem?

I'd go call them and ask if the cable office has any other brand that
you might find more conducive to polling. Maybe another Terayon.

Do you still have reason to believe you're having a modem/RF problem?
I haven't been following the thread that closely, but I thought you
replaced the modem and still suffer from short term disconnections,
which would lead me to believe the problem is elsewhere.

>What did you mean by flexed? Unscrew and losen the coax connection from

Flex = bend, as in slightly bend, to see if there is a loose
connection.

Yes, his cable modem has been exchanged. However, the quality of the
present Ambit U10C018 is an unknown quantity. Personally I have received
multiple intermittently failing replacement equipment from my own
service provider until I announced my intentions to discontinue my
patronage with any more failed units. Only at that point was an obvious
brand new unit placed in my hands. No more failures then.

The reason for the mild flexing is that a failure was noted when the OP
touched the coax and/or "F" connector at the Terayon cable modem. It
isn't totally clear if this has ceased with the Ambit. The premises
cabling goes back to 2000 and it's undetermined if the cable lengths,
and coax/connector, are well rated or are sufficient for 705 GHz data
service. I'm trying my best to assist our OP in determining the point
of failure without having him to schedule/pay for an ISP technician
calls or an electrician to run known quality RG6 from the demarc to the
cable modem. ...and of course the ISP's local outside plant cabling is
an unknown quantity too, at this time.

The OP's previous posts have shown marginal downstream SNRs (29 dB) that
vary 4 dB and possibly more.

All the immediately interesting readings are on the "Downstream" page.

Although an ideal reading of the Downstream signal level, and SNR, would
be in the midst of a failure, I realize how difficult this may be
without a running script. For right now, lets have you take an
instantaneous reading and relay that. It wouldn't hurt to take just the
downstream signal level and downstream SNR readings hourly or every two
hours or so. We need to establish some kind of a new baseline since the
Ambit modem is now in play. This is important!

>

When you installed the Ambit modem, you screwed the house R.F. cable to
the replacement Ambit modem and tightened its connector, with a 7/16"
open-end wrench or its equivalent, such that the cable's "F" connector
is *slightly* more than finger tight. Now you should be able to observe
your systems when you ever so *slightly* bend the R.F. cable back and
forth taking note whether anything fails. We are looking for an
intermittent connection - either in the cable, at the connector, or in
the cable modem at the coax connector.

I did ask for Motorola since someone told me that it was a good brand,
but the gal said no and she said Ambit was the only one.

I assume it is not the modem since the symptoms are the same like my old
Terayon cable modem from 2005. Someone suggested to try without my old
Netgear RT311 router with a direct connection (have to wait for other
house members not to use the Internet much) or another router (might be
able to get an used Linksys to test it). I already tried different cat5
cables (new vs. old) between the router and cable modems.

I flexxed/bented the cable part 360 degrees in circle (didn't force it
hard) while holding the modem so it won't move. It didn't disconnect me.
I checked my cable modem's logs to verify (no errors).

Mine looks new, but how can I be sure that it is not refurbished, used,
etc.? I noticed the logs said defaults used or something (cleared the
logs a few days ago so I can't paste what I saw).

That issue seems to be gone (it better be) hence forced me to swap
modems. I just have these random quick disconnections (1 second long). I
don't know what yesterday's longer disconnections were. They might have
been something else.

Yep, it was that long ago. Oy, that cable service was horrible back
then. Much worse than I am going through because everything on their
side for the whole city (not DOCSIS!) until 2003(?), Adelphia upgraded
the cable infrastrucutre in the city.

When you say plant, is that the little green box in the ground? If so,
then there's one across the street from where I am.

Oy! Copying, pasting, and tweaking is annoying from seven ASP Web pages.
I think I am going to do screen captures next time.

See anything interesting? I noticed this Ambit modem provides more
details than my previous modems. I guess that's good for us to have more
details?

In broad brush strokes, I'm using some terms from my own earlier career.
Loosely speaking, inside plant would be any and all equipment your
service provider has before the signals leave their building(s).

<http://en.wikipedia.org/wiki/Inside_plant>

Again, in the loosest of terminologies, outside plant is the equipment
outside /their/ main building(s) that conveys the signals from them
towards your demarcation point.

<http://en.wikipedia.org/wiki/Outside_plant>

"the little green box in the ground" if it contains any of your
provider's equipment, is part of their outside plant.

The demarcation point, or demarc, is somewhat legal and technical. It's
typically (not always) in/on your property. Equipment on your side of
the demarc is the rate payer's/subscriber's/patron's responsibility.
Even if the original cable company installed your home's coaxial
cabling, you could/should bear the expense of maintenance. This is
an *extremely* gray area. Many cable companies want you to maintain any
and all equipment on your side of the demarc. However, the cable
company techs may be permitted to run new or replace old cabling just to
make the customer happy. However, just as often, the cable company
techs will direct you to use the services of an electrician or imply
that you can DIY.

I would *not* have done this. You may wish to rethink this if you

At the time you took this snapshot of conditions, the "Downstream
Receive Power Level : -1.5 dBmV" is excellent by almost any
standard. Loosely speaking, 0 dBmV is the ideal with a +/- 12 dBmV
range of acceptability.

The "Downstream SNR : 34.4 dB" is acceptable. For QAM256
modulation, a number more positive than 33.0 dB is OK. Would be nicer
if this was more positive than 35 dB. These numbers will vary with time
of day, temperature and many factors in, but mostly out of your control.
When your downstream SNR was 29.0 dB, technically this was 4 dB in the
bad area. Keep monitoring this! I am suspicious that this condition
might yet return!

That is correct. I have gotten the old Linksys that I am going to try

I didn't see anything odd while wiggling, soft bending/flexxing, etc. on
the cable connected to the modem.

Seems like SNR is not changing much before and after. I will keep
watching this for future disconnections.

This is the return/ground/shield of the coaxial unbalanced connection.
It is a very important part in the circuit. The shield is also trying
to keep ambient noise from the other portion of the unbalanced circuit;
the inner conductor.

Notice how the SNRs have almost a 7 dB improvement! Some folks would be
very envious of those numbers.

So it looks like the cable modem swap was worth it. :) Let's just hope
the quick disconnections are from the router or something I can fix
easily.

This log entry seems rather cryptic. I'm wondering if your DHCP lease
was up for renewal, and it initially failed?

Does this coincide with any other connection failures at the same time?

Nope. At that time, I didn't see any disconnections. AND is that clock
even accurate? I remember my old Terayon modem was inacccurate with its
time. I think it was like a few hours off. I haven't figured out the
pattern for this one.

Last one unless you guys want me to post more. I think I got a good
snapshot of the logs now that I have a script to view cable modem's Web
pages at every minute (can't do second or else cable modem blocks my
http requests and I have to manually power cycle the modem).

Running script showed this when connection was working and then got
disconnected again (no route to host; previous disconnetion was at about
12:41 AM PDT):

I am going to stop logging unless you guys think I should get more. My

(haven't gotten an used Linksys router yet to try it yet). I thought I
could do that this weekend, but guess not. :(

Your experiences with a direct [Computer <> Ethernet <> Cable Modem]

Yep, that's my next plan. Just don't have the time. I want to try
another router first so I don't have to wait so long and take other
people offline. :>

The more I think about this, the more I believe this is a DHCP lease
expiring and needing renewal. This is probably not a serious error
but merely a warning message in passing.

OK. I checked again, same exact messages. Nothing new there. Thanks.

It looks like I will be getting an old and used Linksys BEFSX41 4-port
firewall router this Saturday to test my quick disconnet issue. It was
bundled with Norton Internet Security 2003 CD, so I assume it is about
five years old.

It's almost a 100% guarantee that you will require a firmware update.
You may wish to research this and try to determine the present firmware
level and what's available.

Yea. I noticed the latest one is from 2007. That's amazing compared to
my old Netgear RT311. Its latest firmware is v3.25 from 5/4/2001.

Alrighty, I finally got the old Linksys BEFSX41 router hooked up,
upgraded (Firmware Version: 1.52.15), and online.

I just missed another quick disconnection about an hour ago before I
swapped the routers. I will have to wait about another 12-15 hours for
the next one). Let's see how this one goes. If this router still has the
quick disconnections, then I am going back to my old Netgear router
(will sve Linksys one for later when my old Netgear finally dies :P).

Does anyone know how to let my Internet IP address be pingable from the
outside? I can't seem to find the option to set that (way more
configurations than my old Netgear RT311). I wan't able to find it via
Google search (all internal pings).

Thank you in advance. :)

I think it's on page 25 of the user guide, where they talk about the
items on the Security tab. Disable the option called Block WAN
Requests.

It was "Block Anonymous Internet Requests". However, I am having
problems keeping my IRC connections stable. According to the router's logs:

2008-10-18 22:17:12 1586/TCP from [deleted IRC sever's IP address]:6667
to 192.168.0.22:1586 Invalid TCP packet received, dropping packet

Note: I changed from 192.168.1.xxx to 192.168.0.xxx so I didn't have to
reconfigure the computers and stuff. :)

Well, so far I haven't seen any random annoying quick disconnections
that aren't caused by me. However, is too early to conclude that it is
fixed since I have been tweaking my router (requires to drop
connections) most of the day yesterday and Saturday night. I haven't had
seen the random disconnections during the hours I didn't tweak like
Sunday's midnight to Sunday's 10 AM PDT, and Sunday's afternoon to now).

My current issue, with this Linksys router, is having problems keeping
my text-based IRC clients (BitchX, ircii, and Epic4) staying connected
online. They keep getting disconnected after five minutes or so.
Ironically, GUI-based clients (e.g., Pidgin, Trillian Basic, and
SeaMonkey) do NOT have this problem. I don't understand why that
happens. It is quite frustrating since I use IRC a lot through SSH
connections and I prefer text-based clients, especially when I am not at
my computers. I never had this problem with my old Netgear RT311 router
(might have to go back to it if I want text-based IRC or get a brand new
router).

I wonder why my old router had random quick disconnections. Old age
perhaps? :(
